Be it known that We, ARTHUR E. JERRAM, Josrrrr G-oULnnoURN, and FRE HICKS, subects of the King of England, residing at ilieicester, in the county of Leicestershire, England, have invented certain Improve ments in Pulling-Over Machines, of which the following description, in connection with the accompanying drawings, is a speci-; fication, like reference characters on the drawings indicating like parts in the several figures.

This invention'relates to machines for pulling uppers over lasts and more particularly tomachines including in their organization upper pulling'means and fastening mechanism for securing the margin of the upper on the bottom of the last, this application being a division of our prior application SeriafNo. 122,631, filed on September 28, 1916 wherein are claimed per se'certain features of the fastener feeding and driving means hereinafter described.

Features of the present invention reside in a novel organization of upper pulling and fastening means and means forelfecting transfer or feed of a fastener or fasteners at a predetermined time in the cyc-l'e'of the machine, the machine herein shown being so constructed as to pull the upper over a last positioned bottom downward and" having mechanism which is operative at a predetermined time relatively to the operation of the upper pulling means to] deliver fas eners pointupward to the fastener driv- In one of its lmportantjnovcl.

be made for an understandingof details not hereinafter fully; described." In ,-order"=t o assist in understanding the present invlen tion, certain general features of construction or. the illustrative machine, some of which formthe subject-matter of Letters Patent 9 No. 1,23%,256 granted on July 13, 1920 upon an applicz-ition of F red Hicks and a gncd to the as; nee of thisinvention, will first be briefly described, and where convenient the reference characters of the prior Patent No. 663,77'l', and in certain instances also of Patent No; 1,029,387, will be used to indicate corresponding parts.

;lhe'operative parts of the machine are sp'ported upon a frame comprising front and rear plates 2 and i; respectively, connected by stay'rods 6. Bolted to the front frame plate 2 and suitably supported at the top of the rear plate 4-, is the head portion 8 of the machine upon which are mounted the various instrumentalities for operating upon the shoe, and operating means for such instrumentalities comprising the cam shaft D which in the present construction is sup-- ported vertically with its driving pulley 986 in a horizontal position between the frame plates The operation of the machine is controlled by a treadle X connected to one end of a lever X to the other end of which pivoted a short red X which serves in the manner described in said prior patents upon the operation of the treadle, to actuate automatic means for retracting a brake shoe 982 from the pulley 986, such means acting through a rod X' and a lever X to operate a red 98 1- whereby the clutch .(not shown) is actuated to cause the pulley 986 to be driven by means of a suitable belt to etlect the first portion of the cycleof operations of the machine, after which the clutch is automatically disconnected and the brake applied through the connections above described by such means as are fully disclosed prior Patent No. 663,777.

When the work is in position in the machine the last, with the upper positionloosely upon it,- is supported, as indicated by dotted lines in 1, with the rear portion of the upper on the last .in engagement with a heel rest 10 and with the flfore part of. the sole or insole on the last positioned upon a sole rest 12. In this positionthe upper is en gaged by the usual toe and side grippers, of which the toe gripper is seen at le in. Fig. l, and is pulled over the last automatically during the first portion of the cycle oft-operations, the machine then coming automatically to a stop. The toe gripper is connected to an updraw lever e which is pivoted on a rod and has connection at its rear end through a rod 170 and a spring 176 with a cam slide 172 operated by a cain on the cam shaft 1). Through movement of the slide 172 the toe gripper is thus operated to pull the upper yieldingly with a force determined by the degree o'l compression of the spring 176. Tue side grippers are similarly operated by levers 154i pivoted on he rod 152 and connected through springs 146 and rods toa slide 134. During a subsequent portion of the cycle, which takes place upon another depression of the treadle X the margin of the upper is carried inwardly under the bottom 01'. the last and, following .movement of driver bar arms 67:2, 674; and 676 inwardly under the last bottom, the tacks are driven to retain the upper in its pulled-over position. While the machine is at rest after the first period t the cycle,'the operator is afforded opportunity to effect such change of tension or such adjustment of the upper on the last as may be necessary in order to correct any inaccuracy in its position, through the manipulation of various instrumentalities of which it is only necessary herein to rei'er to handles 158 which comprise upwardly and forwardly curved extensions of the side gripper levers 15 i, and a handle 6 comprising a similar extension oi the toe gripper operating lever 9, whereby the operator is enabled to manipulate the different grippers as desired. Pivoted on the handle to the usual lover 226, whereby the opening of the toe gripper my be effected.

The work position rig means and the op erating instriunentalities above described are so arranged in the machine shown that the heel end of the last supported substantially over the front frame plate 2 of the machine and the last inclined upwardly from its heel end toward the rear of the m achine at such an angle that th operator, as he maintains a natural attitude at the front of the machine may without special effort, loolr l l and forwardly upon the downwardly top and sides: of the torepart of the upper on the last and keep the work continuously in view in this manner until the operations are completed. The various instrumented ties whereby adjustment of the upper may be effected, comprising; particularly the handles 1.58 and 0 together with the lover 226 are, moreover, arranged in such relation to the work and to the position of the operator that he may manipulate them. without the necessity of changing materially his viewpoint with. reference to the work and without in any way obstructing}; his view of the work. in order to insure these results the handles referred to are preferably extended, as shown, to positions somewhat higher than the work and far enough forwardly to permit the operator to manipulate them without steeping. .ln the construction shown the last is positioned at an incline of substantially 50 degrees to the horizontal, this angle having been determined as particularly satisfactory for the objects in view under average working condition but it should be understood, that the invention is not limited to a construction in which the last inclined the precise angle shown. It will be observed by reterence to Fig. 1

fastener.

that the operative portions of the machine are substantially at the rear of a verticalin number to the number of tacks to be driven at each operation, upon which the tacks hang suspendedin rows by them heads.

' The tack pot 400, in the construction shown,

is supported upon a bracket 18 and is rotated from the cam shaft D through conhave their. usual movement toward :and from driving positionswith respect'to the margin ofthe lastbottom. v)Vith reference nections including a bell-crank 20 and a link 22. Mounted to reciprocate in the usual manner at the lower ends of the raceways are separator plates '24 (Fig. 7) which are so formed 5) that when the tack,

shown at a, has been advanced to the inner end of the groove 26, it is still suspended by its head and is not permitted to drop' through the usual opening 562 in separator plate 558 (Fig. 6) as heretofore constructed. The tack, as thus supported, is moved into alignment with an opening 28 in thebracket plate 30 which serves to support the raceways. Communicating with this opening at its lower end is a pipe 32 which leads to a valve 8% arranged tofc ontrol the admission tot-he pipe 32 of compressed air from asup; ply'pipe'36which may'communicate'with an air pump or'wi th any suitable supplyof .air under pressure. The construction shown comprises a single pipe 32 leading-to the several openings 28, but it will be under stood that several conduits 32 may be arranged to communicate with the several openings ii desired. Positioned over the separators 24 is a bar 38 provided with openings 40 which are over the heads of the re spcctive tacks after the latter have been moved by the members 24 to separatedjposition. Associated with each of the openings 40 is a block 42 pivoted to the bar 38 and having an opening" 44 arranged to aline with the opening 40 when theblock 42 is in the position shown in Fig. 7 a-nd'in full. lines in Fig. 8. Raceway covers 46 rest up;

on theblocks 4-2, and upon the lifting of any one of these covers the corresponding block wedged therein.

Supported at one end in the bar38 and communicating with the respective openings 40 are curved conduits 48 which lead to various points ,ofydelivery or; presentation $0 1 1 ta k tel rmit t e to be entai ed to the different tack driving instrumentalities. 'The conduits 48 are," it will be understood, equal in number to the numberof tacks to be driven at each. operation and are grouped and arranged required with reference to the particular points which the tacks are to be driven vin the work, the

delivery endsot those conduits beingsup ported on brackets 50'on the machine frame.

W iththis construction and arrangement,a .blastor" compressedalr from the p1pe 32w1ll lift the tacks from the separator plates12 l and force them headforemost into and conduits 4.8 causing the tacks I in. their passage to become inverted in such manner I to be finally presented polnt upward.

The driver bar. arms 672, 67 676 v to Figs. 9 and; 10, the driver bar arm 676, which is one of the side arms having means for drlvlng two tacks simultaneously in the side margin of the last bottom, is arranged for movement toward the left into position to drive the tacks and toward the right away.

position to be driven upon the operative movement of the drivers. -When'the driver bar arm is moved to its inoperative position, which is toward the right in Figs. 9 and 10, the stud 68, in co-operation with toe surface 66, permits the plate 52 to be swung by the spring about the axis 5%- to the dotted line position 1.0), in which the pockets 56 are in line with the delivery ends of the conduits 1-8. While the transfer plate is in this position tacks are forced through the conduits d8 and deposited, point upward, in the pockets 56 in the manner hereinbefore described. lVhile the tack transferring means is illustrated in detail in its relation to only one oi? the driver bar arms, it will be understood that each of the arms has similar mechanism associated therewith.

In order to control the admission of compressed air to the conduit 32, the valve 34: is connected to a short shaft 72 upon which is secured a hub 7 provided with diametrically opposite ratchet teeth 76. lriountcd loosely on the shaft 72 is an arm 78 provided with a spring pressed pawl 80, the arm 78 being rigid with. a pinion 82 which is arranged to be turned in opposite directions alternately by the movement or a rack bar 8%. The bar 84: is arranged to be moved toward the right 1) during the pullingniovement of the grippers in the first period ofthe cycle ofoperations Off the ma chine through connection of the bar with one of the side lever updraw rods by means of an angled arm 86 which is fast on the rod and bears at its outer end upon a collar 88 on the bar 84. During this movement, whereby the pawl is turned about the hub 7a to cause it'to engagethe diametrically opposite teeth 76 without operating the valve 3d, aspring 90 on the bar 84 is compressed and av dog 92 on the bar 8 is caused to engage a spring catch 9%, whereby the rack bar is retained in the position to which it is moved. In the latter part of the final period of the cycle of operations of the machine the return out the arm 86 efiected by the return movement of the grip per operating cam slide ldcauses a trip 96 on the arn'rto engage the catch 94 and withdraw it from the dog 92 against the pressure of itsspring in such manner as to permit the spring 90 to l'orce the rack bar toward the left and efliect an opening and closing movement of the valve 34, movement of the rack bar in this direction being retarded by -Jeans of a dash pot 98. In this manner a blast of air is forced through the pipe 32 and the tacks are delivered pneumatically point upward to the carrier plates at a time when these plates are positioned to receive them while the driver bar arms are in their retracted positions away from the shoe.

In the use of the machine the operator stands close to the front trams plate 2 in position to operate the treadle X. The work, positioned within easy reach of the perator, as indicated in dotted lines in Fig. 1, is below the level or the operators eyes and is inclined at such an angle to atlford the operator full view of the top of the upper and the portions round the sides ot the forepart of the last without any special effort upon his part such would cause fatigue. The various handles which fr-- qucntly require manipulation for the purpose of adjusting the upper, including the handles and e are so arranged to be within easy reach of the operator as he stance in the position described with ut obstructing his view oitthe work. pon the first depression of the treadle X the upper is pulled over the last in the well known manner through the 'on of the gripp at the same time the rack bar 84 is tracted in preparation for the subsccgue. operation or" the valve margin of the up per 15 ca ried inwardly under the last bottcm. the driver bar arms move inwardly causing the plate 52 to swing about their pivots and carry the tacks into alinement with the drivers, and through the operation or the drivers the tacks are driven upwardly into the upper and the sole or innersole. The driver bar arms are then swung outwardly and cause the pockets 56 ag in to aline with the conduits 48, and sbstantially simultaneously, as the grippers are returned to starting positier the 3-iis opcuit d in the manner "l to can. Q the several tacks supx ted on the separator plateii t to be lifted l forced through the conduits 4-8 and defied point upward in the pockets 55 arrive in alinement with the conduits in time to receive the tacks.

Although the invention has been described with reference to a particularly illustrative embodiment, i wll be understood that various modifications in details are contemplated within the spirit and scope oi the claims.

it should be understood that the term inverted, except where the context requires a more limited interpretation, is used herein in a relative sense r ferring to subs antial reversal of the posi i n of a fastener end for eno irrespective of any particular position which the fastener may occupy prior to such reversal.
